The wires must be stripped back and soldered into an Atari joystick connector as follows: SEGA GUN ATARI JOYSTICK PORT Blue wire Pin 1 stick FWD Gray wire Pin 6 trigger Green wire Pin 7 +5 volts Black wire Pin 8 Ground Because of the close fitting connections for the XEGS ports, don’t wire in a DB9 female connector that has “ears”.
